Rituximab is a genetically engineered chimeric monoclonal antibody that targets CDpositive B lymphocytes from early pre-B-cells to later in the differentiation process, but it is absent in terminally differentiated plasma cells.

The binding to CD20 enables rituximab to deplete subpopulations of B lymphocytes by way of cell-mediation, complement-dependent cytotoxicity, and the promotion of apoptosis and growth arrest. Rituximab treatment has been linked with rare cases of progressive multifocal leukoencephalopathy PML.

Belimumab is a monoclonal anti-B lymphocyte stimulator BLyS antibody. It binds to soluble human BLyS with high affinity and inhibits its biological activity. The BLyS mechanism of action of is importance in the survival of B cells, and its inhibition can lead to the apoptosis of autoimmune B-cell clones. Other promising CD targeting antibodies obinutuzumab, ibritumomab, ocaratuzumab need more clinical trials. The strategy of depth of depletion of B cell populations may not be the better way compared with the inhibition of B-cell modulatory cytokines.

Abatacept is a T-cell co-stimulation modulator and a fully human soluble fusion protein that consists of the extracellular domain of human CTLA-4, which is linked to the modified Fc part of human IgG1.

Introduction

Upon antigen recognition, T-cells require a costimulatory signal for full activation. Unlike other biologic drugs, it does not inhibit inflammatory proteins but blocks the communication between these cells by attaching to their surface. It is available in an infusible or injectable form and is administered to patients who have an inadequate response to one or more DMARDs. By contrast, targeting T cells using ciclosporin, anti-CD4 antibodies, anti-CD5 antibodies, or alemtuzumab have not yielded clinically robust responses in patients. The function of T cells and its subsets needs to be further reexamined.

Tocilizumab TCZ is a humanized monoclonal antibody that targets the IL-6 receptor, which is found on cell surfaces and in circulation. IL-6 is produced by various cell types, including T cells, B cells, monocytes, fibroblasts, and endothelial and synovial cells. In the pathology of RA, IL-6 can stimulate pannus formation through increased vascular endothelial growth factor expression and increase bone resorption as a result of osteoclastogenesis, as well as oxidative stress in leukocytes.

Its immunogenicity risk is low. The most common adverse effects observed in clinical trials were upper respiratory tract infections, nasopharyngitis, headaches, and high blood pressure. Clinical trial data are promising and suggest that anti-IL-6 agents could be a promising therapy. IL-1 is a cytokine that has the capability of immune and pro-inflammatory actions. In serum, both IL-1 receptors can bind IL-1, thereby regulating the bioavailability of the cytokine. Anakinra rHuIL-1ra is a non-glycosylated recombinant form of the IL-1 receptor antagonist used as a once daily injectable.

It is different from the native human protein by having an additional N-terminal methionine. Its disadvantage includes the requirement of daily injections, and an itchy rash may be observed at the injection site. However, anakinra should not be used in combination with anti-TNF agents. Its side effects include gastrointestinal tract reaction and allergy and infection of the upper respiratory tract; thus, it should be monitored carefully.

Other IL cytokines and their receptors have been studied as the potential target: IL inhibitor Secukinumab was finished in a phase III study displaying improvement in patients with active RA who had an inadequate response to TNF inhibitors. Denosumab DMab is a human monoclonal IgG2 antibody that inhibits bone resorption by binding and inhibiting the receptor activator of the NF-kB ligand RANKL , an essential cytokine for osteoclastogenesis and bone resorption. Indeed, the presence of local and systemic bone loss in RA patients raised the possibility that the inhibition of RANKL may be an effective strategy to limit pathologic bone resorption.

Phase III trials are required to discern the magnitude of the inhibitory effect on bone erosions and help to establish an optimal dose. Ultimately, DMab may prove to be a promising drug in the treatment of RA. Many cytokines use the Janus kinase JAK and signal transducer and activator of transcription STAT pathway to exert their effect in the pathology of RA, rendering them amenable to therapeutic blockade with Jakinibs which have proven effective for the treatment of RA.

It has moderate activity on tyrosine kinase 2 TYK2 and negligible activity on JAK-3 in both enzymatic and cellular assays.

Data Protection Choices

Baricitinib also proved effective in radiological progression. The new Jakinibs with more restricted JAK isoform selectivity are now between phases 2 and 3 of clinical development. It is advised that jakinibs will require clinical and laboratory vigilance. With a better understanding of the pathophysiology of RA, new therapeutic approaches are emerging to provide precision medicine for individuals. However, the function and adverse side effects of these drugs will need to be carefully evaluated and used reasonably.

To prevent disease onset or relapses, smoking cessation or avoiding body exposure to environment risk factors is probably the easiest and most cost-effective method. Autoimmunity tolerance break develops years before the inflammatory phase of the disease, which can be considered as a golden period for preventing disease progression.

Reestablishing immune tolerance and immunological homeostasis are ambitious goals in the way to overcome the disease. T cells and B cells can be targeted by specific drugs in the future to achieve seroconversion or delay the onset of joint destruction. Reduction of the function of APCs and modification of the pro-inflammatory properties of antibodies are being further developed.

This article has been cited by other articles in PMC. Abstract Rheumatoid arthritis RA is a chronic systemic autoimmune disease that primarily affects the lining of the synovial joints and is associated with progressive disability, premature death, and socioeconomic burdens. Introduction Rheumatoid arthritis RA is a chronic systemic autoimmune disease that arises more frequently in females than males, being predominantly observed in the elderly. Open in a separate window.

Maturation stage This stage is initiated at the site of secondary lymphoid tissues or bone marrow. Targeting stage The involvement of RA in joints usually has a characteristic presentation with synovitis occurring in symmetrical small joints. Fulminant stage Hyperplastic synovium Synovium is characterized by a mixture of bone marrow-derived macrophages and specialized FLSs. Cartilage damage Cartilage acts as a key component of synovial joints, consisting of chondrocytes and a dense and highly organized extracellular matrix ECM synthesized by these chondrocytes and contains type II collagen and glycosaminoglycans GAGs.

Bone erosion Bone loss is a pathological hallmark of RA and manifests as localized, periarticular and systemic bone loss. Systemic consequences Multiple studies have documented an elevated risk of cardiovascular events in RA patients. Modern RA pharmacologic therapies The identification of a preclinical stage and a growing understanding of the natural history and mechanisms of RA development, alongside new potential therapeutic interventions, shapes the prospect that RA might be prevented in future. Table 1 Modern pharmacologic therapies for rheumatoid arthritis.

Gastrointestinal tract, skin, central nervous system adverse effect and retinal toxicity. Infection pneumonia and atypical tuberculosis injection-site reaction. Adalimumab Hypertension. Infection, hypertension, hypogammaglobulinemia, viral reactivation, vaccination responses. Ofatumumab Late-onset neutropenia. Infection, malignancy. Infections most notably skin and soft tissue , increases in serum cholesterol, transient decreases in neutrophil count and abnormal liver function.

Injection site reactions, infections, neutropenia, malignancy. Infections, nasopharyngitis, candidiasis, neutropenia, safety data of mental health is limited. Safety file needs further research. Zoster infection advice is to vaccinate beforehand and other potential side-effects should be monitored carefully through further study.

Leflunomide Leflunomide reduces inflammation in the joints of RA patients by inhibiting dihydroorotate enzymes essential for producing DNA and RNA, particularly in activated proliferation lymphocytes. Hydroxychloroquine In RA, hydroxychloroquine is designed to interfere with the interaction between T helper cells and antigen-presenting macrophages that cause joint inflammation and decrease the production of pro-inflammatory cytokines, thus reducing the overall inflammatory response.

B-cell depletion and inhibition antibodies Rituximab is a genetically engineered chimeric monoclonal antibody that targets CDpositive B lymphocytes from early pre-B-cells to later in the differentiation process, but it is absent in terminally differentiated plasma cells. T-cell targeted therapies Abatacept is a T-cell co-stimulation modulator and a fully human soluble fusion protein that consists of the extracellular domain of human CTLA-4, which is linked to the modified Fc part of human IgG1. IL-6 inhibition Tocilizumab TCZ is a humanized monoclonal antibody that targets the IL-6 receptor, which is found on cell surfaces and in circulation.
